which the followiiig. is a, specification.

The present invention relates to cultivating machines and has rmits object t-o provide an improved soil and stubbleY-turning device which, when suitably adjusted, will Work also as a deep-soil disintegrator, .to efiect the digging up and turnihg of the soil to be .cultivated'not only on the surface but also to any-desired deptln'with the minimum expenditure of power and in less time than was previously possible, without the progress of the work being interfered with by obstacles such as roots, stones, etc. ulof damage being caused by the latter;

The improved'device consistssubstantially of a thin disk disposed in a. vertical plane and rotating ata great speed in the direction ofthe travel of the machine. The said disk is provided-on both sides with half hoeplates perpendicularthereto which are uniformly and symmetrically distributed thereon and arranged tangentially to the direction of rotation: two corresponding half hoe-plates, one at each side of the disk,

forming a complete hoe. ()n the disk behind each hoe are arranged blades also perpendicularto the disk but inclined at an angle of about 50 or to the hoe plate'a'nd ad-- 'justable in radial direction. The said disk is mounted on a. horizontal shatt in such manner that the disk rests with its edge on the soil by, its own weight and is free to move in a vertical direction.

The hoes enter easily into theground previously. scored by the disk and cut and turn the soil in rapidsuccession. whilethe blades folloying the hoes thoroughly disintegrate and scatter the soil. It very hard obstacles (stonesu metals, etc.) are encountered by the disk, the latter is raised thereby and simply rolls oyer them so that no damage or stoppage can be caused. l

The improved siil turning and deep soll disinteo'rating devit'e is illustratedin Figure 1 in side elevation and in Fig. 2 in plan.

The disk at is carried by the cultivating machine, which may be of any known self-propelling type, on a shaft 6 in such manner that the disk :;ilways rests with its edge upon the ground and can move freelyup and down notwithstanding the chain drive. The device may be attached to a cultivating machine in any suitable manner.

The medias operamli of the improved deride is as follows :-If the soil is to be thoroughly dug o and turned, the blades cl on the disk a must be fixed nearer the ClIClliD? ference of the latter so that their extreme edges lie exactly in the path of the hoes 0, 0 The blades d, d being fixed in this position,

the disk a is rapidly rotated in the direction of the arrow 1, while the machine and therefore the disk simultaneously receive continuous motion in the direction ofthe arrowII.

In consequence of the rapid rotation (300 revolutiohs and more per minute), theedge of the disk (4 bearing freely 'on the ground with its own weight, scores the soil: the hoes c, a cut in rapid succession through the soil previously scored by the disk a.- Advancing in layers farther into the ground, while'the blades (Z, (Z following each hoe, disintegrate and rake atonce the layers of earth just cut,

The improved device works consequently -1 in the manner of a millingcutter. If obstacles such as roots, wood, soft stones, etc., are encountered by the disk a, they are partly cut up and removed by the hoes and blades byabrasion. If the obstacles are too hard 1'10 thedisk a simply rises in passing over them.

If, however, only the upper layeref t Soil a layersare only: to. be loosened," the blades d d on the disk 0 must be fixed closer to the shaftb so that their extremeedges lie a circle smaller than, the 'path of the, hoes; Qonsequent1y,Iifthe device-is operated inthe "same-manner as above described,' there will be. an-annular zone betw'ejenthe" aths of the I I chlnes forturning' soil and stubble'and disblades 'an'd hoesft'he soil in whic -,-although 'cut' up and loosened by the hoes, is. not
